Police who responded to the scene hit Johnson at least five times with their clubs, threw him over the guardrail, applied pressure points to his ears and armpits, and Tased him twice, Johnson's wife Linda Johnson alleges in her lawsuit.

Linda Johnson is suing the Maryland State Police and Baltimore County Police, as well as the departments' top commanders and the officers she holds responsible.

Johnson claims police should have known her husband was suffering from a medical condition since his wallet contained a medical alert card about his diabetes.

After Carl Johnson was Tased, he became "motionless and speechless," according to the lawsuit.

He died of cardiac arrest within an hour, Courthouse News Service reported.
